Solved: Three sinusoidal waves of the same frequency
Chapter 16, Problem 69(choose chapter or problem)
Three sinusoidal waves of the same frequency travel along a string in the positive direction of an x axis. Their amplitudes are Yl> y1/2, and y 1/3, and their phase constants are 0, 7T/2, and 7T, respectively. What are the (a) amplitude and (b) phase constant of the resultant wave? (c) Plot the wave form of the resultant wave at t = 0, and discuss its behavior as t increases.
